Disconnect pad wires and put an ohmeter across the outboard (pad
wire) contacts. There should be continuity if the wear sensor wires
are OK. If OK, then what about the harness (inboard wires)? One way
to test the harness is to jumper both sets of contacts, which should
eliminate the warning light if _both_ sets of harness wires are OK.
If/when one harness is bad, I'm not sure how best to identify it,
although the Bentley probably has a procedure.

You're referring to the "warning light" on the LCD panel, right? The
other (lower) light is unrelated to pad-wear sensor.

Hey Bernie, those are good for another 0.4" of wear, right? ;-)

with a car whose PO snipped off both the _inboard_ sensor connectors
in order to use pads without wear sensors!
